Abstract

The predominant effect of catecholamines in general, and of epinephrine in particular, on motor activity of rabbit intestinal smooth muscle, is an inhibition of spontaneous contractile activity and a decrease in tone. This present investigation was initiated through an accidental observation that after in vitro reserpinization epinephrine appeared to hasten recovery of contractile activity of isolated rabbit jejunum. Although there have been a few published reports of stimulation of contractile activity of rabbit intestine by low concentrations of epinephrine, the observation of a stimulant effect of epinephrine after in vitro reserpinization has never been reported in the literature.
